Whilst the fiftieth anniversary of the beginning of knowledge idea was once celebrated on the 1998 IEEE foreign Symposium on Informa­ tion thought in Boston, there has been loads of mirrored image at the the yr 1993 as a severe 12 months. because the years move and extra perspec­ tive is received, it's a relatively secure wager that we are going to view 1993 because the 12 months whilst the "early years" of mistakes keep watch over coding got here to an finish.
